Challenge Problems
Push your limits with challenges.
Question 1
A newly designed building has a mass that is unevenly distributed. Describe how this affects its performance during an earthquake.
💡 Hint: Consider the effects of uneven distribution.
Question 2
Calculate the change in natural frequency for a structure if its mass increases from 2000 kg to 2400 kg, assuming the stiffness remains constant and initially the natural frequency is 2 Hz.
💡 Hint: Use the formula for natural frequency: f = 1/(2π)√(k/m).
